Yes, sonny- straight bear oil for hunting patches. In cold weather, the bear grease becomes quite stiff and hard, but the pure oil doesn't, which is why some guys separate it.
Fat from around the organs is the best for producing oil. Marmot oil is even better than bear oil, it just takes a few marmots to get a gallon or so. Fall is the best time to shoot them, if it's legal, that is. The fat from around the innards of a marmot produces very few solids when 'tried 'out and virtually no grease - just pure clear oil - incredible stuff.
